- Buy and hold BTC, keep it simple. Quit job when you can live from 4% of your wealth and sell a few years worth of BTC at that point to stomach the volatility

- Regular health checks: you will start having health problems, but nobody knows what exactly

- Dating may get harder in 10 years, decide fast if you want wife/children

- eating the same amount of food that you did will get you fatter. You can balance it of course.

I guess that's it, so enjoy being 30, I loved it :)
